Shiharam is one of the best bosses at that point in the game. His Tomahawk and full guard make it a bad idea to try and combat him with archers and mages, and his Stun skill can be lethal if activated. If you can take him out with a spear or tomahawk, or some other ranged weapon, do so. But be ready to take his place, or another enemy will.

Ike: You're the enemy general, right?Shiharam: I am.Ike: I lead the Crimean army. My name is Ike. I know this is sudden, but can we end this battle?Shiharam: What?Ike: I'd like you to shut the floodgates. There's no need to involve the locals in our combat, is there?Shiharam: ...I'm sorry, but I can't do that. Until one of us has fallen, the water will continue to flow.Ike: If that's how it has to be, then I have no choice. Prepare yourself.Shiharam: Ha! So that's the enemy general, eh? If he's the man he appears to be, I can die knowing that Jill is safe.

Jill: Father...Shiharam: We meet as enemies. There are no pleasantries to exchange. Ready your weapon, soldier of Crimea!Jill: Father... I...Shiharam: You won't charge? Then I will bring the fight to you!

Shiharam: A sacred pegasus knight, eh? At one time, we both protected the same country.Tanith: So you're the one who led the defection to Daein, Lord Fizzart! The man I heard tales about and the reality of what I see before me are quite different.Shiharam: Tales?Tanith: It said that after the last apostle died, the corrupted senate drove one man to leave Begnion. He was said to be in search of a better life, and he became a hero to many young wyvern riders.Shiharam: Hah, that's rich... Tales always make too much of their subjects.Tanith: I had been looking forward to meeting you in the flesh—perhaps even to speaking with you. But now... You would sacrifice the lives of your people just to slow our progress? What kind of dangerous fool are you?Shiharam: ...Tanith: I will not allow you to besmirch the name of Begnion's wyvern riders any further. Prepare yourself!
